The more contemporary Honda F1s were also released by Tomica.

This is the Lotus 99T - in individual packaging, they come as No.11.
The boxed set below has the No.12.

The famous McLaren MP4/4 in #12

Here
is a set - these cars were not available individually - the ones in this
set are sequentially numbered up from the individually boxed ones.
The fact that they appear in a set makes them even more rare. Of this
set of 4, only 2 of them are Honda powered.

Here is another Tomica box set - this time of Honda F1 cars only. This
set contains the Williams Honda No.6, Lotus Honda No. 12 and the Honda
F1 RA 301 No. 18. All are not available individually.
